The independent security review after the arson attack at the Governor’s Residence will be conducted by a former State Police Commissioner. Jeffrey Miller will lead the investigation into how the suspect was able to scale an about seven-foot-tall fence and set a fire inside the home while Governor Josh Shapiro and his family were sleeping. Miller served with PSP for 24 years and now owns a private security consulting company. Shapiro said last week he believes the review is warranted and will only help the department.
